Notes

Although this is the recommended official release version, we suggest that you only use Blender 2.49 for import/export only.

We recommend using Blender 2.7+ for production work.

Use a recommended exchange format (.3ds, not .obj) or the .blend file set to compatibility mode to move between Blender versions.
